Apple Inc became the first $1 trillion publicly listed U.S. company on Thursday, capping a decade-long rise in its stock price fueled by its ubiquitous iPhone.
The tech company's stock jumped 2.8 percent, bringing its gain to about 9 percent since Tuesday when its reported June-quarter results above expectations and announced it bought back another $20 billion worth of stock in the latest quarter.
